It looks like humanities hope of turning Mars into a second Earth may never translate into reality thanks in part to the red planet’s lack of a magnetic field.
Scientists have discovered that our Sun’s solar radiation may thwart all attempts at increasing the atmospheric pressure of the crimson world, which means we may never get the chance of witnessing a green Mars, let alone a blue one.
(Discovery News) Scientists have identified a sort of double-whammy solar super wave that is responsible for blowing away air from Mars and keeping its atmosphere thin, frigid and downright inhospitable for any possible future travelers.
The waves happen when one stream of solar wind is overrun and amped up by another, faster gale of solar particles. That creates a flying traffic jam of particles that slam into Mars as one large pulse. [...]
When Edberg and his colleagues compared these events at Mars to the flow of heavier atoms blowing past Mars Express, they discovered that fully a third of Martian air loss happens during the 15 percent of the time when doubled-up solar wind pulses hit the planet.
Although this means that Mars may never become a second eden (unless we can create a global magnetic field), it does not mean that humanity will never settle the planet en mass.
Future colonists will have to adapt to living within specialized biospheres (with portable magnetic shields to protect them from radiation), although doing so is probably much cheaper than terraforming the entire planet.

Paraterraformation…exactly!
Since it is far easier to achieve a small area of paraterraformation, this will be the first type of terraforming of Mars. Paraterraformation can easily be scaled until eventually you have a worldhouse. So, why is there so much more discussion about terraforming than paraterraforming?
Probably because world house’s are not as familiar.
I think bio domes might be a better approach (fiscally speaking) as constructing a world house would be very expensive.
The most complex thing with colonization of mars is that it is having very low magnetic field..you remember solar storm could devast terraformed martian colonies.
Can we exchange links? I have added yours.
Hey Bruce,
Sure, I’ll add you to the side bar!
As far as the magnetic field goes, that will probably be the biggest hindrance to a Martian settlement.
